one, which is nearly erect. Lip large, pendent, ovato-ob- 
long, remarkably concave, inflated, slipper-shaped, pale 
reddish-brown, with dark dots placed in lines; below, it 
terminates in two tooth-like pomts, and these are, above, 
covered by a pale, almost whitish lamina, having a tuft of 
yellow hairs at the base, and a few brown spots: it is some- 
times as long as, sometimes shorter than, the two teeth, 
sometimes bifid at the point ; at other times, as in the pre- 
sent specimens, quite entire. Column large, dilated, con- 
vex, oval, petaloid, rose-coloured. Anther white, cordate, 
inserted just within the point of the column. Pollen masses 
four, ovate, compressed, in two pairs, the under ones the 
smallest, fixed upon a large white membranous base. 
I have, on a former occasion*, stated it, as my opinion, 
that the American and European Calypso should only be 
considered as one species, and the present figures, drawn 
from living plants, sent from Montreal, by Mr. CLecuorn, 
seem to confirm this opinion, having the two teeth of the 
labellum as short, if not shorter than the lamina, which has 
been given, by Mr. Brown, as the essential character of the 
European plant. Spreneen again, relying probably on my 
figures in Exotic Flora, has made a principal character of 
the C. Americana to depend on the bifid lamina; but, in 
the present individuals, that is quite entire as in SwaRtz’s 
figure. So that we see, even in the same country, that the 
structure of the flower is liable to vary. Our plants flow- 
ered in a cool pert of the greenhouse, in the latter end of 
March, being kept in the same earth and the same box, 10 
which the roots were imported the preceding year. 
It appears to be a general inhabitant of the northern 
parts of Europe and America. In Canada it is common. 
Dr. Ricuarpson and Mr. Drummonp found it about Lake 
Erie; Mr. Menzies at Nova Scotia; Governor Lewis and 
Mr. Scouter on the north-west coast of America. Its 
beauty must recommend it, as highly deserving a place i 
every collection.
